Physics 222 Fall 2011 Name:_______________ Section:______________ Quiz 11A 1. With a polarizing filter how can you check if the light entering your eye from a particular direction is polarized or not? 2. Two ideal polarizers are oriented at 65 degrees to one another. Unpolarized light falls on them. What fraction of the light intensity is transmitted?

Physics 222 Fall 2011 Name:_______________ Section:______________ Quiz 11B 1. When completely unpolarized light is incident on a polarizing filter that is in a particular orientation, ideally 50% of the light is transmitted through the filter. However, when the filter is rotated by 90 degrees from its initial orientation, how much light will now be transmitted? 2. Two ideal Polaroids are aligned so that the light passing through them is a maximum. At what angle should one of them be rotated so that the intensity is subsequently reduced by half?

Unformatted text preview: 1. The phonomenon of total internal reflection can only occur when light is traveling in a material with a higher index of refraction as compared to the outside material it is trying to travel into. Does Brewsters law, refering to the polarization of light by reflection have this same restriction? 2. Two ideal polarizers are oriented at 65 degrees to one another. Unpolarized light falls on them. What fraction of the light intensity is transmitted? Physics 222 Fall 2011 Name:_______________ Section:______________ Quiz 11D 1. An electromagnetic wave in vacuum is moving in the positive z direction. If the magnetic field component of this wave oscillates in the y direction, then what is considered the direction of polarization for this wave? 2. Two ideal Polaroids are aligned so that the light passing through them is a maximum. At what angle should one of them be rotated so that the intensity is subsequently reduced by half?...
